WOODEN PUMP.

SPECIFICATION forming part of Letters Patent No. 251,939, dated January 3, 1882.

Application filed March 21, 1881. (No model.)

To all whom it may concern Beit known that I, CHARLES POWE L, of the city of Toronto, in the county of York, in the Province of Ontario, Canada, manufacturer, have invented new and useful Improvements in Wooden Pumps, of which the following is a specification.

The object of the invention is to produce a cheaply-constructed, strong, and effective com- 7 bined force and lift pump; and it consists in the peculiar construction and arrangement of parts, as more fully hereinafterdescribed, and then pointed out in the claims.

The drawing represents a perspective view of a pump provided with my improvements.

A is the body of the pump, which may be of any suitable design, but as shown in the drawing has a cast-iron centerpiece, of which the spout B forms part. This center-piece is made in accordance with an invention of mine already patented.

O is the tubing, extending below the platform and connected together in the usual manner with coupling X. I place in the coupling X, at any convenient joint in the tubing, a casing, D, preferably made of light galvanized iron, and provided with a drop-pipe or casing, E, extending from the top to its bottom and forming a passage-way for the pump-rod F. This drop-pipe or casing E should be the same diameter as that of the general bore of the tubing, while the diameter of thelarger casing D should be as large as it can conveniently be made within the coupling in which it is placed. The pump-plunger is at a point below this casing or air-chamber D, and as it forces the water up the tube in the usual way the water enters the air-vessel D, compressing the air at its top, which air expands when the upward movement of the plunger ceases, and by exerting a pressure due to its expansion upon the water within the air-vessel forces the water up the tubing.

While there are several advantages which I might specify in having the air-vessel located within the barrel of the pump, as shown, it will be sufficient to say that as my invention relates more particularly to wooden pumps, which are usually made in all small country places, it is a great advantage to offer small By placing the air-chamber in the coupling X, as shown in the drawing, the ends of the pump-tubing, fitting in theends of the coup ling, serve to secure it firmly in place without other fastenings. The inner pipe of the airchamber, being of the same diameter as the bore of the tubing, allows the piston to be removed from the pump through said pipe without disturbing the air-chamber.

The means for operating this pump are composed of a spindle or pin, G, which forms a pivotal point for the handle H, and is supported upon a vertical rod, I, which is pivoted at any suitable point on the body of the pump, preferably, as shown in the drawing, upon a pin or lug attached to the iron portion of my pump-body. On the opposite side of the swinging lever I attach to the end of the spindle G a brace, J, which I extend obliquely to a point outside of the body of the pump, preferably, when the pump is constructed as shown, upon a lug or pin attached to the spout B, at which point it is also pivoted. As

shown in the drawing, the bottom of the vertical rod is pivoted on a line with the pivotal point of the oblique brace J, the two points being connected together by a horizontal spindle, K, the ends of which t'orm thepoints upon which the rod I and brace J are pivoted.

The means above described for operating the pump I do not claim in this application, as I intend it to form the SllbjQClJ-lnitttGIYOf a separate application for a patent.

What I claim as my invention is-- 1. The air-chamber D, in combination with the coupling X, having openings to receive the ends of the main pump-tubes, substantially as and for the purpose described.

2. In apump in which the piston-rod reciprocateswithin its tubing, the air vessel or chamber D, placed within said tubing and provided with a central pipe inclosing the piston-rod,

said pipe being of substantially the same intially the same internal diameter as the bore ternal diameter as the bore of the tubing, subof the pump-tubing, substantially as and for 10 stantially as and for the purpose set folrith. the purpose described.

3. In combination with the coupling hav- 1 1 I 5 ing a central opening to receive the air-cham- (JHARLES POWELL ber D and the ends of the pump-tubes, the air- Witnesses: chamber D, closely fitting in said coupling and DONALD O. RIDOUT, provided with a central pipe E, of substan- G. W. BALDWIN.
